On my wall is the front page of Daily Express of September 5, 1945 and the words: “I write this as a warning to the world.” So began Wilfred Burchett’s report from Hiroshima. It was the scoop of the century. For his lone, perilous journey that defied the US occupation authorities, Burchett was pilloried, not least by his embedded colleagues. He warned that an act of premeditated mass murder on an epic scale had launched a new era of terror.

Almost every day now, he is vindicated. The intrinsic criminality of the atomic bombing is borne out in the US National Archives and by the subsequent decades of militarism camouflaged as democracy. The Syria psychodrama exemplifies this. Yet again, we are held hostage to the prospect of a terrorism whose nature and history even the most liberal critics still deny. The great unmentionable is that humanity’s most dangerous enemy resides across the Atlantic.
